Black Hole Rush Support
A fast-session arcade growth game. You are a small black hole loose in Gravity City. Everything you swallow makes you bigger, and everything bigger than you is a threat — until it isn't.

Reporting a problem
Please include as much of this as you can — it usually turns a week of guessing into a same-day fix:
- Device model and OS version
- Which phase the match was in when it happened
- What you expected versus what happened
- Steps to reproduce
- Whether it happens every match or occasionally
Common questions
Does the game need an internet connection?
No. Everything runs on your device, including the rival holes, which are bots.
Are there in-app purchases or ads?
Neither. Everything unlockable is cosmetic and earned by playing.
Is my progress saved anywhere else?
No. Saves are local to the device, with an automatic recovery copy in case of a corrupted write.
Is it multiplayer?
Matches are against five on-device bots. Online multiplayer is not part of the current release.
What are the accessibility options?
Reduced motion, high contrast, adjustable text size, handedness, camera shake control, and separate music, effects and haptics sliders.
Which devices are supported?
iPhone, iPad and Android phones and tablets, in landscape.
Privacy and data requests
Black Hole Rush is a completely offline game. It collects no data, contains no advertising, has no analytics and makes no network connections.
Because nothing leaves your device, there is no account to close and no server-side data for us to export or delete. To remove everything the app has stored, delete the app from your device. Full detail is in the Black Hole Rush privacy policy.
